FIELD OF THE INVENTION

This invention is in the field of tomato plants.

BACKGROUND OF THE INVENTION

Tomato is an important global crop. Several plant species associated with the family Solanaceae have been familiar to mankind since ancient times and are of great agricultural importance. The genus Solanum is a member of the Solanaceae family and includes the domesticated tomato S. lycopersicum (also known as Lycopersicum esculentum). Tomato is generally adapted to warm summer growing conditions but can also be grown in heated greenhouses under winter conditions. The introduction of hybrid tomato cultivars in the 1950s provided a magnitude of benefits including increased yield, better holding ability, adaptation to expanded growing seasons through the use of protected cultivation and improved disease resistances, which resulted in large-scale production of tomato as a commercial crop.

Tomato breeders make continual improvements in hybrid tomato yield, horticultural characteristics, and consumer quality traits. Thus, there is an ongoing need for improved tomato hybrid varieties and parental lines.

SUMMARY OF THE INVENTION

According to the invention, there is provided a novel hybrid tomato variety, designated Monile, also known as T316108, and parental tomato line AI1D13TEN000015.

The invention also encompasses the seeds of tomato hybrid T316108 and line AI1D13TEN000015, the plants of tomato hybrid T316108 and line AI1D13TEN000015, plant parts of the tomato hybrid T316108 and line AI1D13TEN000015 (including fruit, seed, gametes, rootstock, scions, shoots), methods of producing seed from tomato hybrid T316108 and line AI1D13TEN000015, and methods for producing a tomato plant by crossing the tomato hybrid T316108 or line AI1D13TEN000015 with itself or another tomato plant, methods for producing a tomato plant containing in its genetic material one or more transgenes, and the transgenic tomato plants produced by that method.

It should be appreciated that the invention can be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Unless the context indicates otherwise, it is specifically intended that the various features and embodiments of the invention described herein can be used in any combination.

Moreover, the present invention also contemplates that in some embodiments of the invention, any feature or combination of features set forth herein can be excluded or omitted. To illustrate, if the specification states that a composition comprises components A, B and C, it is specifically intended that any of A, B or C, or a combination thereof, can be omitted and disclaimed singularly or in any combination.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety.

Definitions.

In the description and tables that follow, a number of terms are used. In order to provide a clear and consistent understanding of the specification and claims, including the scope to be given such terms, the following definitions are provided:

As used in the description of the invention and the appended claims, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

As used herein, “and/or” refers to and encompasses any and all possible combinations of one or more of the associated listed items, as well as the lack of combinations when interpreted in the alternative (“or”).

The term “about,” as used herein when referring to a measurable value such as a dosage or time period and the like, is meant to encompass variations of ±20%, ±10%, ±5%, ±1%, ±0.5%, or even ±0.1% of the specified amount.

The term “comprise,” “comprises” and “comprising” as used herein, specify the presence of the stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

As used herein, the transitional phrase “consisting essentially of” means that the scope of a claim is to be interpreted to encompass the specified materials or steps recited in the claim “and those that do not materially affect the basic and novel characteristic(s)” of the claimed invention. See, In re Herz, 537 F.2d 549, 551-52, 190 U.S.P.Q. 461, 463 (CCPA 1976) (emphasis in the original); see also MPEP § 2111.03. Thus, the term “consisting essentially of” when used in a claim or the description of this invention is not intended to be interpreted to be equivalent to “comprising.”

“Added trait”: As used herein, a desired “added trait” or “additional trait” can be any trait that confers a desired characteristic to the plant, and may be introduced by any method known in the art, e.g., conventional breeding (for example, backcrossing), gene editing, mutagenesis, or genetic transformation techniques. Examples of added traits include without limitation: male sterility, male fertility, herbicide resistance, pest (e.g., insect and/or nematode) resistance, modified fatty acid metabolism, modified carbohydrate metabolism, disease resistance (e.g., against bacterial, fungal and/or viral disease), abiotic stress tolerance, enhanced nutritional quality (e.g., increased flavonoid content of the fruit), improved appearance (e.g., external fruit color and/or fruit flesh color), increased fruit sweetness, increased fruit flavor, improved fruit ripening, improved texture or taste, improved fruit yield, improved seed yield, improved seedling vigor, improved seed germination, industrial usage, gene editing machinery, or any combination thereof. The trait can be encoded by a DNA sequence (e.g., native tomato sequence, induced or naturally occurring mutation, edited native sequence, or a transgene) or can result from expression of a functional non-translated RNA (e.g., RNA interference).

“Allele”. An allele is any of one or more alternative forms of a gene, all of which relate to a trait or characteristic. In a diploid cell or organism, the two alleles of a given gene occupy the corresponding locus on a pair of homologous chromosomes.

“Backcrossing”. Backcrossing is a process in which a breeder repeatedly crosses hybrid progeny back to one of the parents (the “recurrent” parent), for example, a first generation hybrid F₁ with one of the parental genotype of the F₁ hybrid.

“Cotyledon”. One of the first leaves of the embryo of a seed plant; typically one or more in monocotyledons, two in dicotyledons, and two or more in gymnosperms.

“Determinate”: Determinate tomato plants tend to be compact and bushy in form, and the plant produces all of its fruit simultaneously within a short period of time (e.g., one to three weeks), and then fruit production stops.

“Double haploid line”. A stable inbred line achieved by doubling the chromosomes of a haploid line, e.g., from anther culture. For example, some pollen grains (haploid) cultivated under specific conditions develop plantlets containing 1n chromosomes. The chromosomes in these plantlets are then induced to “double” (e.g., using chemical means) resulting in cells containing 2n chromosomes. The progeny of these plantlets are termed “double haploid” and are essentially not segregating any more (e.g., are stable). The term “double haploid” is used interchangeably herein with “dihaploid.”

“Essentially all of the physiological and morphological characteristics”. A plant having “essentially all the physiological and morphological characteristics” (and similar phrases) means a plant having all of the desired physiological and morphological characteristics of hybrid T316108 or line AI1D13TEN000015, except for the characteristic(s) derived from a converted locus/loci (e.g., a single converted locus), for example, introduced via backcrossing to hybrid T316108 or line AI1D13TEN000015, a modified gene(s) resulting from genome editing techniques, an introduced transgene (i.e., introduced via genetic transformation techniques) or mutation, when both plants are grown under the same environmental conditions. In embodiments, a plant having “essentially all of the physiological and morphological characteristics” means a plant having all of the characteristics of the reference plant with the exception of five or fewer traits, 4 or fewer traits, 3 or fewer traits, 2 or fewer traits, or one trait. In embodiments, the plant comprising “essentially all of the physiological and morphological characteristics” of variety (e.g., for tomato hybrid T316108, a strong generative plant type with good consistent setting, mature fruit with a shiny pink color and flesh, a small uniform fruit size, and/or an oval plum shape or any other trait described herein, e.g., in Table 1; and for tomato line AI1D13TEN000015, a mature fruit with a yellow skin color, a uniform yellow mature fruit flesh and/or an oval plum shape or any other trait described herein, e.g., in Table 1).

“First water date”. The date the seed first receives adequate moisture to germinate. This can and often does equal the planting date.

“Gene”. As used herein, “gene” refers to a segment of nucleic acid comprising an open reading frame. A gene can be introduced into a genome of a species, whether from a different species or from the same species, using transformation or various breeding methods.

“Gene editing”: “Gene editing” (sometimes also called “genome editing”) refers to the introduction of targeted modifications into genomic DNA using techniques employing, for example, meganucleases, zinc-finger nucleases, TALENs, and CRISPR/Cas9 systems. See, e.g., Gaj et al., ZFN, TALEN, and CRISPR/Cas-based methods for genome engineering. Trends in Biotechnology, 31:397-405 (2013).

“Inbred line”: As used herein, the phrase “inbred line” refers to a genetically homozygous or nearly homozygous population. An inbred line, for example, can be derived through several cycles of sib crossing and/or selfing and/or via double haploid production. In some embodiments, inbred lines breed true for one or more traits of interest. An “inbred plant” or “inbred progeny” is an individual sampled from an inbred line.

“Indeterminate”: Indeterminate tomato plants tend to be vine-like, and will grow and produce fruits throughout the season (e.g., until killed by frost).

“Plant.” As used herein, the term “plant” includes plant cells, plant protoplasts, plant cell tissue cultures from which plants can be regenerated, plant calli, plant clumps, and plant cells that are intact in plants or parts of plants, such as leaves, pollen, embryos, cotyledons, hypocotyl, roots, root tips, anthers, pistils, flowers, ovules, seeds, fruit, stems, and the like.

“Plant material”. The terms “plant material” and “material obtainable from a plant” are used interchangeably herein and refer to any plant material obtainable from a plant including without limitation, leaves, stems, roots, flowers or flower parts, fruits, pollen, ovules, zygotes, seeds, cuttings, cell or tissue cultures, or any other part or product of the plant.

“Plant part”. As used herein, a “plant part” includes any part, organ, tissue or cell of a plant including without limitation an embryo, meristem, leaf, pollen, cotyledon, hypocotyl, root, root tip, anther, flower, flower bud, pistil, ovule, seed, shoot, stem, stalk, petiole, pith, capsule, a scion, a rootstock and/or a fruit including callus and protoplasts derived from any of the foregoing. In representative embodiments, the plant part is a non-propagating plant part, for example, is not a seed.

“Quantitative Trait Locus”. Quantitative Trait Locus (QTL) refers to a genetic locus that control to some degree, numerically representable traits that are usually continuously distributed.

“Regeneration”. Regeneration refers to the development of a plant from tissue culture.

“Resistance”. As used herein the terms “resistance” and “tolerance” (and grammatical variations thereof) are used interchangeably to describe plants that show reduced or essentially no symptoms to a specific biotic (e.g., a pest, pathogen or disease) or abiotic (e.g., exogenous or environmental, including herbicides) factor or stressor. In some embodiments, “resistant” or “tolerant” plants show some symptoms but are still able to produce marketable product with an acceptable yield, e.g., the yield may still be reduced and/or the plants may be stunted as compared with the yield or growth in the absence of the biotic and/or abiotic factor or stressor. Those skilled in the art will appreciate that the degree of resistance or tolerance may be assessed with respect to a plurality or even an entire field of plants. A tomato plant may be considered “resistant” or “tolerant” if resistance/tolerance is observed over a plurality of plants (e.g., an average), even if particular individual plants may be susceptible to the biotic or abiotic factor or stressor.

Tissue Culture.

In embodiments, tomato plants can be propagated by tissue culture and regeneration. Tissue culture of various plant tissues and regeneration of plants therefrom is well known. For example, reference may be had to Teng, et al., HortScience, 27:9, 1030-1032 (1992); Teng, et al., HortScience, 28:6, 669-1671 (1993); Zhang, et al., Journal of Genetics and Breeding, 46:3, 287-290 (1992); Webb, et al., Plant Cell Tissue and Organ Culture, 38:1, 77-79 (1994); Curtis, et al., Journal of Experimental Botany, 45:279, 1441-1449 (1994); Nagata, et al., Journal for the American Society for Horticultural Science, 125:6, 669-672 (2000); and Ibrahim, et al., Plant Cell Tissue and Organ Culture, 28(2), 139-145 (1992). It is clear from the literature that the state of the art is such that these methods of obtaining plants are routinely used and have a high rate of success. Thus, another aspect of this invention is to provide cells which upon growth and differentiation produce tomato plants having desired characteristics of tomato hybrid T316108 or line AI1D13TEN000015. Optionally, tomato plants can be regenerated from the tissue culture of the invention comprising all or essentially all of the physiological and morphological characteristics of tomato hybrid T316108 or line AI1D13TEN000015.

As used herein, the term “tissue culture” indicates a composition comprising isolated cells of the same or a different type or a collection of such cells organized into parts of a plant. Exemplary types of tissue cultures are protoplasts, calli, meristematic cells, and plant cells that can generate tissue culture that are intact in plants or parts of plants, such as leaves, pollen, embryos, roots, root tips, anthers, pistils, flowers, seeds, petioles, suckers, and the like. Means for preparing and maintaining plant tissue culture are well known in the art. By way of example, a tissue culture comprising organs has been used to produce regenerated plants. U.S. Pat. Nos. 5,959,185, 5,973,234, and 5,977,445 describe certain techniques.

Additional Breeding Methods.

This invention is also directed to methods for producing a tomato plant by crossing a first parent tomato plant with a second parent tomato plant wherein the first and/or second parent tomato plant is a plant of tomato hybrid T316108 or line AI1D13TEN000015. Thus, any of the following exemplary methods using tomato hybrid T316108 or line AI1D13TEN000015 are part of this invention: selfing, backcrosses, hybrid production, crosses to populations, double haploid production, and the like. All plants produced using tomato hybrid T316108 or line AI1D13TEN000015 as at least one parent are within the scope of this invention, including those developed from tomato plants derived from tomato hybrid T316108 or line AI1D13TEN000015. Advantageously, tomato hybrid T316108 or line AI1D13TEN000015 can be used in crosses with other, different, tomato plants (e.g., inbred lines)to produce first generation (F₁) tomato hybrid seeds and plants with desirable characteristics. The tomato plants of the invention can also be used for transformation where exogenous transgenes are introduced and expressed by the plants of the invention or for introduction of genetic changes by gene editing or mutagenesis. Genetic variants created either through traditional breeding methods, gene editing, mutagenesis or transformation of the cultivars of the invention by any of a number of protocols known to those of skill in the art are intended to be within the scope of this invention.

The following describes exemplary breeding methods that may be used with tomato hybrid T316108 or line AI1D13TEN000015 in the development of further tomato plants. One such embodiment is a method for developing tomato hybrid T316108 or line AI1D13TEN000015 progeny tomato plants (e.g., a diploid progeny tomato plant) in a tomato plant breeding program comprising: obtaining a plant, or a part thereof, of tomato hybrid T316108 or line AI1D13TEN000015, utilizing said plant or plant part as a source of breeding material, and selecting a tomato hybrid T316108 or line AI1D13TEN000015 progeny plant with some, all or essentially all morphological and/or physiological characteristics of tomato hybrid T316108 or line AI1D13TEN000015 (see, e.g., Table 1), respectively, optionally with the use of molecular markers. In representative embodiments, a progeny plant of tomato hybrid T316108 has at least 1, 2, 3, 4 or more of the morphological and physiological characteristics of tomato hybrid T316108 (for example, produces a mature fruit having a shiny pink skin color, a pink mature fruit flesh, oval plum shape, an average weight of about 10 grams, and an excellent taste). In embodiments, a progeny plant of tomato line AI1D13TEN000015 has at least 1, 2, 3, 4 or more of the characteristics of tomato line AI1D13TEN000015 (for example, produces a mature fruit having a yellow skin color, a uniform yellow fruit flesh, oval plum shape, an average weight of about 9 to 10 grams, and an average diameter of about 2.8 cm). In embodiments, a progeny plant of tomato hybrid T316108 or tomato line AI1D13TEN000015 comprises essentially all or even all of the morphological and physiological characteristics of tomato hybrid T316108 or line AI1D13TEN000015, respectively so that said progeny tomato plant is not significantly different for said traits than tomato hybrid T316108 or line AI1D13TEN000015, respectively, as determined at the 5% significance level when grown in the same environmental conditions; optionally, with the presence of one or more desired added traits. Breeding steps that may be used in the breeding program include pedigree breeding, backcrossing, mutation breeding, recurrent selection and/or double haploid production. In conjunction with these steps, techniques such as RFLP-enhanced selection, genetic marker enhanced selection (for example, SSR markers) and/or and the making of double haploids may be utilized.

Another representative method involves producing a population of tomato hybrid T316108 or line AI1D13TEN000015 progeny plants (e.g., diploid progeny plants), comprising crossing tomato hybrid T316108 or line AI1D13TEN000015 with another tomato plant, thereby producing a population of tomato plants that, on average, derives at least 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% of its alleles (i.e., TAC) from tomato hybrid T316108 or line AI1D13TEN000015, e.g., at least about 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% of the genetic complement of tomato hybrid T316108 or line AI1D13TEN000015. One embodiment of this invention is the tomato plant produced by this method and that has obtained at least 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% of its alleles (i.e., TAC) from tomato hybrid T316108 or line AI1D13TEN000015, and optionally may be the result of a breeding process comprising one or two breeding crosses and one or more of selfing, sibbing, backcrossing and/or double haploid techniques in any combination and any order. In embodiments, the breeding process does not include a breeding cross, and comprises selfing, sibbing, backcrossing and or double haploid technology.

One of ordinary skill in the art of plant breeding would know how to evaluate the traits of two plants to determine if there is or is not significant difference between the two traits expressed by those plants. For example, see Fehr and Walt, Principles of Cultivar Development, pp. 261-286 (1987). Thus, in embodiments, the invention includes tomato hybrid T316108 progeny tomato plants characterized by e.g., 1, 2, 3, 4 or more characteristics of tomato hybrid T316108 as described herein, e.g., produces a mature fruit having a shiny pink skin color, a pink mature fruit flesh, oval plum shape, an average weight of about 10 grams, and an excellent taste. In embodiments, the invention includes tomato line AI1D13TEN000015 progeny tomato plants characterized by 1, 2, 3, 4 or more of the characteristics of tomato line AI1D13TEN000015 as described herein, e.g., produces a mature fruit having a yellow skin color, a uniform yellow fruit flesh, oval plum shape, an average weight of about 9 to 10 grams, and an average diameter of about 2.8 cm. In embodiments, the selected progeny comprises all or essentially all the morphological and physiological characteristics of tomato hybrid T316108 or line AI1D13TEN000015 (e.g., a described in Table 1). In embodiments, the invention encompasses progeny plants having a combination of at least 2, 3, 4, 5, 6, 7, 8, 9, 10 or more of the characteristics as described herein for tomato hybrid T316108 or line AI1D13TEN000015 (see, e.g., Table 1), so that said progeny tomato plant is not significantly different for said traits than tomato hybrid T316108 or line AI1D13TEN000015, respectively, as determined at the 5% significance level when grown in the same environmental conditions. Using techniques described herein and those known in the art, molecular markers may be used to identify said progeny plant as progeny of tomato hybrid T316108 or line AI1D13TEN000015. Mean trait values may be used to determine whether trait differences are significant, and optionally the traits are measured on plants grown under the same environmental conditions.

Progeny of tomato hybrid T316108 or line AI1D13TEN000015 may also be characterized through their filial relationship with tomato hybrid T316108 or line AI1D13TEN000015, as for example, being within a certain number of breeding crosses of tomato hybrid T316108 or line AI1D13TEN000015. A breeding cross is a cross made to introduce new genetics into the progeny, and is distinguished from a cross, such as a self or a sib cross or a backcross to either tomato hybrid T316108 or line AI1D13TEN000015 as a recurrent parent, made to select among existing genetic alleles. The lower the number of breeding crosses in the pedigree, the closer the relationship between tomato hybrid T316108 or line AI1D13TEN000015 and its progeny. For example, progeny produced by the methods described herein may be within 1, 2, 3, 4, 5 or more breeding crosses of tomato hybrid T316108 or line AI1D13TEN000015. Those skilled in the art will appreciate that a progeny of hybrid T316108 is also a progeny of parental line AI1D13TEN000015, just the generational relationship is different.

In representative embodiments, a tomato plant derived from tomato hybrid T316108 or line AI1D13TEN000015 comprises cells comprising at least one set of chromosomes derived from tomato hybrid T316108 or line AI1D13TEN000015. In embodiments, the tomato plant or population of tomato plants derived from tomato hybrid T316108 or line AI1D13TEN000015 comprises, on average, at least 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% of its alleles (i.e., TAC) from tomato hybrid T316108 or line AI1D13TEN000015, e.g., at least about 6.25%, 12.5%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 80%, 85%, 90%, 95%, 96%, 97%, 98% or 99% of the genetic complement of tomato hybrid T316108 or line AI1D13TEN000015, and optionally may be the result of one or more of selfing, sibbing, backcrossing and/or double haploid techniques in any combination. In embodiments, the tomato plant derived from tomato hybrid T316108 or line AI1D13TEN000015 is one, two, three, four, five or more breeding crosses removed from tomato hybrid T316108 or line AI1D13TEN000015.

In representative embodiments, a plant derived from tomato hybrid T316108 or line AI1D13TEN000015 is a double haploid plant, a hybrid plant, an inbred plant, and/or a diploid plant.

In embodiments, a derived plant from tomato hybrid T316108 or line AI1D13TEN000015 comprises a desired added trait. In representative embodiments, a tomato plant derived from tomato hybrid T316108 or line AI1D13TEN000015 comprises all of the morphological and physiological characteristics of tomato hybrid T316108 or line AI1D13TEN000015 (e.g., as described in Table 1). In embodiments, the tomato plant derived from tomato hybrid T316108 or line AI1D13TEN000015 comprises essentially all of the morphological and physiological characteristics of tomato hybrid T316108 or line AI1D13TEN000015 (e.g., as described in Table 1), with the addition of a desired added trait.

Those skilled in the art will appreciate that traits can be introduced into tomato hybrid T316108 or line AI1D13TEN000015 by any method known in the art, e.g., plant transformation methods, conventional breeding, gene editing and/or natural or induced mutations.

Further Embodiments of the Invention.

With the advent of molecular biological techniques that have allowed the isolation and characterization of genes that encode specific protein products, scientists in the field of plant biology developed a strong interest in engineering the genome of plants to contain and express foreign nucleic acids including additional or modified versions of native (endogenous) nucleic acids (optionally driven by a non-native promoter) in order to alter the traits of a plant in a specific manner. Any nucleic acid sequences, whether from a different species, the same species or an artificial sequence, which are introduced into the genome using transformation or various breeding methods, are referred to herein collectively as “transgenes.” Over the last fifteen to twenty years, several methods for producing transgenic plants have been developed, and in particular embodiments the present invention also relates to transformed versions of tomato plants disclosed herein.

Genetic engineering techniques can be used (alone or in combination with breeding methods) to introduce one or more desired added traits into plant, for example, tomato hybrid T316108 or line AI1D13TEN000015 or progeny or tomato plants derived thereof. Once a transgene has been introduction into a plant by genetic transformation, it can be transferred to other plants via conventional breeding.

Plant transformation generally involves the construction of an expression vector that will function in plant cells. Optionally, such a vector comprises one or more nucleic acids comprising a coding sequence for a polypeptide or an untranslated functional RNA under control of, or operatively linked to, a regulatory element (for example, a promoter). In representative embodiments, the vector(s) may be in the form of a plasmid, and can be used alone or in combination with other plasmids, to provide transformed tomato plants using transformation methods as described herein to incorporate transgenes into the genetic material of the tomato plant.

Additional methods include, but are not limited to, expression vectors introduced into plant tissues using a direct nucleic acid transfer method, such as microprojectile-mediated delivery (e.g., with a biolistic device), DNA injection, Agrobacterium-mediated transformation, electroporation, and the like. Transformed plants obtained from the plants (and parts and tissue culture thereof) of the invention are intended to be within the scope of this invention.

Expression Vectors for Plant Transformation—Selectable Markers.

Expression vectors typically include at least one nucleic acid comprising or encoding a selectable marker, operably linked to a regulatory element (for example, a promoter) that allows transformed cells containing the marker to be either recovered by negative selection, e.g., inhibiting growth of cells that do not contain the selectable marker, or by positive selection, e.g., screening for the product encoded by the selectable marker. Many commonly used selectable markers for plant transformation are well known in the transformation art, and include, for example, nucleic acids that code for enzymes that metabolically detoxify a selective chemical agent which may be an antibiotic or an herbicide, or nucleic acids that encode an altered target which is insensitive to the inhibitor. Positive selection methods are also known in the art.

Commonly used selectable markers in plants include, but are not limited to: neomycin phosphotransferase II (nptII) conferring resistance to kanamycin, hygromycin phosphotransferase conferring resistance to the antibiotic hygromycin, bacterial selectable markers that confer resistance to antibiotics (e.g., gentamycin acetyl transferase, streptomycin phosphotransferase, and aminoglycoside-3′-adenyl transferase, selectable markers conferring resistance to herbicides (e.g., glyphosate, glufosinate, or bromoxynil). Selection of transformed plant cells can also be based on screening presumptively transformed plant cells rather than direct genetic selection of transformed cells for resistance to a toxic substance such as an antibiotic; such markers include without limitation alpha-glucuronidase (GUS), alpha-galactosidase, luciferase, and Green Fluorescent Protein (GFP) and mutant GFPs.

Expression Vectors for Plant Transformation—Promoters.

Transgenes included in expression vectors are generally driven by a nucleotide sequence comprising a regulatory element (for example, a promoter). Numerous types of promoters are well known in the transformation arts, as are other regulatory elements that can be used alone or in combination with promoters.

As used herein, “promoter” includes reference to a region of DNA upstream from the start of transcription and involved in recognition and binding of RNA polymerase and other proteins to initiate transcription. A “plant promoter” is a promoter capable of initiating transcription in plant cells.

Examples of promoters under developmental control include promoters that preferentially initiate transcription in certain tissues, such as leaves, roots, seeds, fibers, xylem vessels, tracheids, or sclerenchyma. Such promoters are referred to as “tissue-preferred.” Promoters that initiate transcription only in certain tissue are referred to as “tissue-specific.” A “cell type” specific promoter preferentially drives expression in certain cell types in one or more organs, for example, vascular cells in roots or leaves. An “inducible” promoter is a promoter that is under environmental control. Examples of environmental conditions that may affect transcription by inducible promoters include anaerobic conditions or the presence of light. Tissue-specific, tissue-preferred, cell type specific, and inducible promoters constitute the class of “non-constitutive” promoters. A “constitutive” promoter is a promoter that is active under most environmental conditions.

Many suitable promoters are known in the art and can be selected and used to achieve the desired outcome.

Signal Sequences for Targeting Proteins to Subcellular Compartments.

Transport of polypeptides produced by transgenes to a subcellular compartment such as the chloroplast, vacuole, peroxisome, glyoxysome, cell wall, or mitochondrion, or for secretion into the apoplast, is generally accomplished by means of operably linking a nucleotide sequence encoding a signal sequence to the 5′ and/or 3′ region of a nucleic acid encoding the polypeptide of interest. Signal sequences at the 5′ and/or 3′ end of the coding sequence target the polypeptide to particular subcellular compartments.

The presence of a signal sequence can direct a polypeptide to either an intracellular organelle or subcellular compartment or for secretion to the apoplast. Many signal sequences are known in the art. See, for example, Becker, et al., Plant Mol. Biol., 20:49 (1992); Close, P. S., Master's Thesis, Iowa State University (1993); Knox, C., et al., “Structure and Organization of Two Divergent Alpha-Amylase Genes from Barley,” Plant Mol. Biol., 9:3-17 (1987); Lerner, et al., Plant Physiol., 91:124-129 (1989); Fontes, et al., Plant Cell, 3:483-496 (1991); Matsuoka, et al., PNAS, 88:834 (1991); Gould, et al., J. Cell. Biol., 108:1657 (1989); Creissen, et al., Plant J, 2:129 (1991); Kalderon, et al., A short amino acid sequence able to specify nuclear location, Cell, 39:499-509 (1984); and Steifel, et al., Expression of a maize cell wall hydroxyproline-rich glycoprotein gene in early leaf and root vascular differentiation, Plant Cell, 2:785-793 (1990).

Foreign Polypeptide Transgenes and Agronomic Transgenes.

With transgenic plants according to the present invention, a foreign protein can be produced in commercial quantities. Thus, techniques for the selection and propagation of transformed plants, which are well understood in the art, yield a plurality of transgenic plants which are harvested in a conventional manner, and a foreign polypeptide then can be extracted from a tissue of interest or from total biomass. Protein extraction from plant biomass can be accomplished by known methods which are discussed, for example, by Heney and Orr, Anal. Biochem., 114:92-6 (1981). According to a representative embodiment, the transgenic plant provided for commercial production of foreign protein is a tomato plant of the invention. In another embodiment, the biomass of interest is seed and/or fruit.

Likewise, by means of the present invention, agronomic transgenes and other desired added traits can be expressed in transformed plants (and their progeny, e.g., produced by breeding methods). More particularly, plants can be genetically engineered to express various phenotypes of agronomic interest or other desired added traits. Exemplary nucleic acids of interest in this regard conferring a desired added trait(s) include, but are not limited to, those transgenes that confer resistance to confer resistance to plant pests (e.g., nematode or insect) or disease (e.g., fungal, bacterial or viral), transgenes that confer herbicide tolerance, transgenes that confer male sterility, and transgenes that confer or contribute to a value-added trait such as increased nutrient content (e.g., iron, nitrate), increased sweetness (e.g., by introducing a transgene coding for monellin), modified fatty acid metabolism (for example, by introducing into a plant an antisense sequence directed against stearyl-ACP desaturase to increase stearic acid content of the plant), modified carbohydrate composition (e.g., by introducing into plants a transgene coding for an enzyme that alters the branching pattern of starch), modified fruit color (e.g., external fruit color and/or fruit flesh), or modified flavor profile of the fruit.

In embodiments, the transgene encodes a non-translated RNA (e.g., RNAi) that is expressed to produce targeted inhibition of gene expression, thereby conferring the desired trait on the plant.

In embodiments, the transgene encodes the machinery used for gene editing techniques.

Any transgene, including those exemplified above, can be introduced into the tomato plants of the invention through a variety of means including, but not limited to, transformation (e.g., genetic engineering techniques), conventional breeding, and introgression methods to introduce the transgene into other genetic backgrounds.

Methods for Plant Transformation.

Numerous methods for plant transformation have been developed, including biological and physical plant transformation protocols. See, for example, Miki, et al., “Procedures for Introducing Foreign DNA into Plants” in Methods in Plant Molecular Biology and Biotechnology, Glick and Thompson Eds., CRC Press, Inc., Boca Raton, pp. 67-88 (1993). In addition, expression vectors and in vitro culture methods for plant cell or tissue transformation and regeneration of plants are available. See, for example, Gruber, et al., “Vectors for Plant Transformation” in Methods in Plant Molecular Biology and Biotechnology, Glick and Thompson Eds., CRC Press, Inc., Boca Raton, pp. 89-119 (1993). Commonly used plant transformation methods include Agrobacterium-mediated transformation and direct transgene transfer methods (e.g., microprojectile-mediated transformation, sonication, liposome or spheroplast fusion, and electroporation of protoplasts or whole cells).

Following transformation of plant target tissues, expression of selectable marker transgenes (e.g., as described above) allows for preferential selection of transformed cells, tissues and/or plants, using regeneration and selection methods now well known in the art.

The foregoing methods for transformation are typically used to produce a transgenic tomato line. The transgenic tomato line can then be crossed with another (non-transgenic or transgenic) line in order to produce a new transgenic tomato line. Alternatively, a transgene that has been engineered into a particular plant using transformation techniques can be introduced into another plant or line using traditional breeding (e.g., backcrossing) techniques that are well known in the plant breeding arts. For example, a backcrossing approach can be used to move an engineered transgene from a public, non-elite inbred line into an elite inbred line, or from an inbred line containing a foreign transgene in its genome into an inbred line or lines which do not contain that transgene. As used herein, “crossing” can refer to a simple X by Y cross, or the process of backcrossing, depending on the context.

Locus Conversions.

When the term “plant” is used in the context of the present invention, this term also includes any locus conversions of that plant or variety. The term “locus converted plant” as used herein refers to those plants that are developed, for example, by backcrossing, genome editing, genetic transformation and/or mutation, wherein essentially all of the desired morphological and physiological characteristics of a variety (e.g., for tomato hybrid T316108, a mature fruit having a shiny pink color, a pink mature fruit flesh, oval plum shape, an average weight of about 10 grams or any other trait described herein, e.g., in Table 1; and for tomato line AI1D13TEN000015, a mature fruit having a yellow skin color, a uniform yellow fruit flesh, oval plum shape, an average weight of about 9 to 10 grams or any other trait described herein, e.g., in Table 1) are recovered in addition to the one or more genes introduced into the variety.

To illustrate, backcrossing methods can be used with the present invention to improve or introduce a characteristic into the variety. The term “backcrossing” as used herein refers to the repeated crossing of a hybrid progeny back to the recurrent parent, e.g., backcrossing 1, 2, 3, 4, 5, 6, 7, 8, 9, or more times to the recurrent parent. The parental plant that contributes the gene for the desired characteristic is termed the “nonrecurrent” or “donor parent.” This terminology refers to the fact that the nonrecurrent parent is generally used one time in the breeding e.g., backcross) protocol and therefore does not recur. The gene that is transferred can be a native gene, a mutated native gene or a transgene introduced by genetic engineering techniques into the plant (or ancestor thereof). The parental plant into which the gene(s) from the nonrecurrent parent are transferred is known as the “recurrent” parent as it is used for multiple rounds in the backcrossing protocol. Poehlman & Sleper (1994) and Fehr (1993). In a typical backcross protocol, the original variety of interest (recurrent parent) is crossed to a second variety (nonrecurrent parent) that carries the gene(s) of interest to be transferred. The resulting progeny from this cross are then crossed again to the recurrent parent and the process is repeated until a plant is obtained wherein essentially all of the desired morphological and physiological characteristics of the recurrent parent are recovered in the converted plant in addition to the transferred gene(s) and associated trait(s) from the nonrecurrent parent.

To illustrate, in embodiments, the method comprises obtaining a sample of nucleic acids from the plant and detecting at least a first polymorphism in the nucleic acid sample. Optionally, the method may comprise detecting a plurality of polymorphisms (e.g., two or more, three or more, four or more, five or more, six or more, eight or more or ten or more polymorphisms, etc.) in the genome of the plant. In representative embodiments, the method further comprises storing the results of the step of detecting the polymorphism(s) on a computer readable medium. The invention further provides a computer readable medium produced by such a method.
